Description

Awhile ago I saw something squeeze a 360mm radiator into a Thermaltake Core G3. For some reason, that just seem really awesome to put a 360mm radiator into a 24L case. Even though Thermaltake calls the G3 an ATX case, it is very much a small form factor case, with the compromises and limitations of a SFF case.

I tinkered quite a bit with the cooling of the case, but finally got it to a point where the temperatures are good. CPU is around 50c for gaming. 67c for synthetic CPU+ GPU benchmarks. GPU stays under 50c even with overclocking. There are three EK Vardar F4 at the front of the case pulling cold air to the radiator, while a single Corsair SP120 intakes more cool air from the top of the case. Case has positive pressure with passive exhaust out the sides and back of the case. The monoblock helps keep the critical motherboard components cool.

The PCIe extender that came with the case did not work. The second extender that I bought online was a higher quality, and works.

Additional components:

  • NZXT Hue

  • NZXT USB 2.0 hub with adapters that connects to rear USB 3.0 ports, since Z270i motherboard has no USB 2.0 headers

  • Silverstone 8 port PWM hub

  • EZDIY PCIe extender

Watercooling components:

  • Alphacool 360mm 30mm thick radiator

  • EK 140 reservoir with D5 pump

  • GTX FE 1080 waterblock

  • Strix 270i monoblock

  • Assorted EKWB and XSPC fittings

  • Primochill soft tubing

  • Distilled water with biocide

well done i think that the cooling systom is harder to make than anything else

Awesome build in such a narrow case. The loop looks great too.

I've ordered this case, and I'm VERY happy to see that a 360mm rad is possible. Your build is beautiful, and a great inspiration!

Hi very nice build. What's the size of the window side panel? Thanks!

Thanks! I’ve moved to a different case for now, and my G3 is in storage, so I don’t have exact measurements of the window. It is smaller than I’d like. The case “border” is around the window about 3” wide, and even wider on the bottom (to cover up the PSU).

Ah okay, I would like to know the exact measurement of the side panel(not only the window). I'm searching for a glass panel for replacement. The case would be perfect for wall mount but it needs some improvements ;D

I know this is an older post. I got this case since it is the only one that is this small that would fit my classified. Working on getting a loop in it as well. Did you have to do much to get the 360 to fit or just take out the hard drive bays?

Also amazing looking build. Hope mine turns out anywhere near this.

Only had to remove the drive bays. Keep an eye out for the front radiator interfering with the snaps of the front cover. Mine broke because I tried bending the snaps to clear the radiator. Thanks!

Nice. I plan to try and stuff a 360 as well as a 120 in the top. Should be enough room for a thin 120 if I use the front of the case as well that they for some reason didn't give you mounting for.

The top fan slot will be very tight for a radiator, a fan, and a graphics card. I’m not sure if it will fit.

I am going to try a thin radiator and see if it will work. Would make cooling a 980ti a lot easier than just a single 360

Nice. How did you mount the pump?

And do you now have any disk storage?

Thanks. The pump is mounted on an EK pump bracket and screw to existing holes on the floor. I have a m.2 boot drive on the motherboard, and a 2.5” SSD taped to the chassis.

Thanks! Definitely need planning, and proper sequence of installing certain items before others: some cables first, followed by hidden tubing / fittings, followed by some main components, remaining cables (small then large), etc. taking it apart will need to be done in the same way, but in reverse sequence.
